Yes, it's certainly addictive!
OK, I do have some feedback if that's OK.
I appreciate that your PC isn't maybe up to video editing, but this depends on what software you are using. I use Adobe Premiere Pro and this will produce proxy files to work with. On my PC (also not really designed to edit video) premiere pro wont work with the original 4K files, but it works fine with 1080. So what happens is it copies the files into a low res version you can work with, and when you render the final product it uses what you have done with the proxy files but applies it to the 4K originals.
So you can use much smaller files to make a smooth editing experience, but have a 4K finished product. It takes a while to produce the proxy files, and a while to render the final output, but you can go and watch TV or whatever whilst it's working. I think there are other programs that work with proxy files to edit, but I'm now used to premiere pro. The proxies I use are 1080 but you can have lower quality and that works fine for editing on a poorly specced PC. If you are trying to edit 4K files directly, most PC's won't work too well - or in my case not at all.
Secondly, drones are about movement. Either the drone has to be moving or the subject has to have movement if the drone is parked. An example being a film I've just finished, I'm riding a bike around local heathland. There are some shots where the drone is parked and I'm cycling across the frame, and some shots without cyclist where the drone is moving over landscape. There are even some shots where both the drone AND me are moving - DJI drones are marvellous! But my point is movement. If nothing is moving, you are looking at a still picture.
I understand you need to get the editing software / hardware sorted first, but when you have, pick the absolute best bits of each shot and try to group them in a logical order. I tend to go for an ascending shot, some flying around shots and finish with a descending one. Also, be ruthless with editing - holding people's attention is hard! Cutting to music helps people have a slightly longer attention span, but avoid duplicate shots.
Hope this helps
